WIF1 and colorectal cancer: Overexpression of miR-181a not only promotes colorectal cancer cell motility, invasion, and liver metastasis, but also plays a potential role in enhancing the EMT by upregulating vimentin and downregulating epithelial markers such as β-catenin and E-cadherin through the suppression of the Wnt inhibitory factor 1 (WIF-1) [134].
